Abstract :
In this paper, the key technology of IEEE 802.11 access mechanism is studied. The two main access mechanism of IEEE 802.11 MAC layer protocol are DCF (Distributed Coordination Function) and PCF (Point Coordination Function). CSMA/CA is the basic media access control mechanism of DCF and RTS/CTS message exchange mechanism is optional. PCF is realized by polling mechanism of Access Point (AP). Virtual carrier sense and random backoff are two main collision avoidance technologies of IEEE 802.11 protocol.
